[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

I’m working on a project involving the need to precisely move a tool based on the measured distance to an object. Okay, yeah, it’s a CNC mill. Anyway, I’d heard of time of fight sensors and decided to ...

Proximity sensing based on infrared signal acquisition and processing typically requires two parts to form the optical front end: an infrared LED and an optical sensor. The infrared LED beams infrared ...

A lot of new cars have fancy cameras on the rear bumper to help you parallel park. If your car doesn't have that feature, DIY blog Mad Science has put together a tutorial to roll your own sensor ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

Sensor technology has been opening doors for everything from precisely measuring the impacts of climate change on sea levels to enabling driverless cars to alerting homeowners when to restock their ...

The vibrating proximity sensor is an amazing infrared proximity detector device that scans a limited area in front of it. When it detects the close proximity of an object within its field of view, a ...

With increased automation of complex production systems, components that are capable of acquiring and transmitting information regarding the production process become necessary. Proximity sensors -- ...
